Ever wondered how many muscles you have in each foot, or how your standard of living compares with that of the average person in Zambia? Brandreth has done an astounding amount of fact- and figure-gathering, and can tell you the answers to these questions (respectively, 20 and extremely favorably) and others. Presenting a physical, social and medical profile of the average human being today, the volume covers such topics as eating habits, sex and marriage, diseases, how the human eye works and the effects of alcohol on the body. Graphs and tables compare rates of illiteracy, divorce, unemployment, suicide and alcoholic consumption in various countries. Brandreth even includes a ""test'' readers can take to determine how long they can expect to live. This diverting compilation of both useless and useful information will be especially appreciated by trivia buffs. (April)
